Asubmarine is at the surface of the ocean, preparing to dive. it submerges and dives to −972 feet. then, it ascends 308 feet to avoid hitting an undersea cliff. what integer represents the submarine's position in feet (depth) after it ascends to avoid the cliff?

answer: carrie scored higher on the standardized test because she got the highest score out of all of them.

hope that

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
